Character Name: Eridan Ampora Super Power/Mutation: The aquatic mutation that only troll sea dwellers have strengthens in Eridan and overrides his ability use his lungs ... So, while he becomes more aquatic in that the fins on his face lengthen and he gains webbed fingers and toes -- Restrictions: -- He can't use his lungs at all and so must depend on those gills he has on his face. Reasoning: Eridan is a sea dweller, a sub-race of troll distinct from the land dweller commoners by mutation. It is also a caste that rules over the entire species... He even has a genocidal complex against land dwellers, yet he's only been in the water a few times his entire thirteen year old life! Obviously, it's time to put him in his place. ... Which is obviously in the water, since now that he can't breathe the oxygen from the air around him like he used to be able to do with his lungs, he'll have to depend a lot on the oxygen that is in the water thanks to his gills. Any last questions? Hopefully this is all right and makes sense? I imagine that he looks like this when it comes to the relation of his pectoral fins (the ones on his face) with his gills, so the fins getting longer would be quite interesting to see him react to.
